When Miguel Hanson and his fiancee, Diana Wesley, get married on Saturday, a computer will conduct the ceremony. Well, technically, a computer program Hanson wrote will serve as the minister.

During the wedding, to be held in the Houston home of Hanson's parents, the couple will stand before a 30-inch monitor in the backyard. In a robotic voice, the computer will greet the guests, say how the couple met and go through the ceremony.

The ceremony won't be legally binding. The couple will still have to get a justice of the peace to sign their paperwork.
